In the construction shown in the drawings, the grain carrying box car 1 is provided with a lateral doorway 2 having an outside door 3 hung on trucks 4 for sliding edgewise on the outside of the car as usual for side doors. In order tohold-the grain independently of the outside door 3, and to facilitate loading and unloading the car,- a supplementary door of novel construction and operation is hinged on the door frame 6, inside of the car, in slightly spaced relation wardly for opening;

The grain door 5 comprises substantially a pair of similar right and left sections or halves, each hinged on vertical edge axes to the adjacent door posts respectively as at 7. The inner edges overlap slightly and are provided with fastenings, three being here shown, each including a hasp 8 secured to yone section, an eye piece 9 secured to the opposite section and a pin 10 to lock said parts together, said pin having a chain 11 to hold it adjacent to the eye piece when not in use.

Each half .of the grain door comprises a plurality of sections, three in this instance,

disposedI one above another including a main section 12 disposed medially, a tope section 13 adapted to'operateI independently of the medial sectionjand a bottom section 14 also adapted to b-e opened and lclosed independ- -ently vof the middle section. The middle dropped down into place, the lower edge itting a groove 14 in the door-sill 1- and the outer side edge iittingbetween the rnedial section and the side post 6, a fastener `15 being 'provided to s ecure` same in place.

The fastener 1-5 is in the formofy a bolt havingy a head 15` formed to serve as a depending handle when in p lace. The sections 14 and` right section 12 are perforated to receive the bolt and section 12 isthreaded to engagel the bolt tip.- i Thisbolt is,` secured" against loss by the `chain 15 secured toe the left section 14. f p

Then a car equippedwith a grain door such as herein described is to befloaded' the medial sections 12 are closed first, the left hand part which is closed first overlapping on the outer side the adjacent edge of the right hand part as at 19, where it is secured by the said fasteners. The lower sections 14 are then slipped down into place and secured by the fastening means 15 at their upper inner corners; Finally the upper sections are leftlopen or are swung open inwardly,

whereupon the grain may be loaded through,

the opening thus provided in the upper part of the doorway. After the car is loaded the upper sections may be swung together and locked by means of the hasp 8 on the left section and eye-piece and pin on the right hand'section. Both of these top sections 13 overlap the inner side medial sections 12 and the left section which is closed first overlaps on the outside the right section. Moreover, a fastener 21 is provided on the right hand section near its lower edge for engaging the medial section 12 on that side.

said fastener being provided in the form of a turn but-ton, one arm of which is made long and is offset to swing downward and out over the top edge of section 12. The doors when thus closed are very securely held and present a rigid construction.

Then the car is to be unloaded, the Jfastener 15 at the upper inner corners of the lower sections 14 is unscrewed, thus releasing said sections which may then be lifted upward by the handles 22 out of their lower edge frame grooves 14 and hung on the hooks Q3 on the middle sections respectively, the sections 14 being apertured at 24 to receive said hooks. This permits the grain to run out by gravity, except that which occupies the lower part of the car. and that may be scraped`r shoveled or otherwise forced out through this lower part of the doorway. The lower sections are then removed from said hooks and lowered into place where they are again secured by said fastener 15 and ,the car is ready to receive another load.

-This grain door is of simple and inexpensive construction, is easy to operate, and can be used readily by unskilled labor. It is designed to take the place of the more eX- pensive and more complicated doors occa sionally used, as well also as the common crude and rough board closures now used very extensively.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims:

I claim- 1. In a railway car a grain door formed and adapted to swing inward substantially and in eect as two sections hinged to the sides of the doorway respectively, each ol' said sections including a medial part and top and bottom parts each movable relative to the medial part, all of said sections being formed and arranged t0 overlap along their several mutually adjacent edges and the two bottom sections being slidable vertically for opening and closing.

2. In a railway car a grain door formed and adapted to swing inward substantially as two sections hinged to the sides of the doorway respectively, each of said sections including a medial part and top and bottom parts each of said top and bottom parts being adapted to open and close relative to said medial part and independently of each other, all of said sections being made thin and formed of sheet metal and all being arranged to overlap along their several mutually adjacent edges and the lowermost sections being movable edgewise vertically for opening and closing.

3. A six part grain door adapted as :i whole to swing open inwardly, said door comprising independently operable right and lett halves, each as a whole mounted on hinges to swing laterally and each of said halves including top, middle, and bottom sections, the said top sections being adapted to Swing inwardly alone to admit grain in loading, and the bottom sections being adapted to open edgewise when the car is 'full of grain independently of the other sections to discharge grain. the said bottom sections being free of said hinge mounting conneetions.
